p LOCKING DEVICE FOR MOTQR-VEHICLES I v To all whom it may concern:

- lie it known that we, CHARLES J. OUELLET and Amos J. OUELLET, citizens of the United States, residing at Cambridge, in the county of Middlesex and State of Massachusetts,

have invented new and useful Improvements in Locking Devic'es'for Motor-Vehicles, of which the following is a SPQCIl'lCfltlOIL This invention relates to improvements in locking devices for motor vehicles and is a provide a locking mechanism for a plurality of moving parts of the vehicle but all of which locking instruinentalities are controlled by a single or a common actuating means The invention consists in the combination and arrangement ofparts whereby the above objects and certain other objects hereinafter appearing may be attained, as set forth in the following specification and particularly pointed out in the claims.

Referring to the drawings, Figure 1 is asection illustrating portionsof the floor,-

frame and operating levers of a motor vehicle-with a device embodying our invention shown in connection therewith. Fig. 2

floor of a motorvehicle preferably of the.

sarily limited to this type of car,-butmay be. attached to any car employing levers for, throwing -1I1 clutches, shifting gears or apk f plying brakes. When applied to the Ford car this device is preferably employed in ings, in a neutral position. "This lever when pulled back as'far as it will go also acts to apply the emergency brake of the vehicle to the rear wheel. This device is also adapted. for use inconnection with another lever 12;

which in the type of machine referred to is operations largely controlled. -When this lever is pressed forward thecli'itcli engages the low speed gear. Whenhalf-way for- .1

ward the gears are in neutral position or disconnected from the drivlng mechanism.

lVhen the hand lever 11 is thrown forward 'high speed gears of the car will be thrown into opera-tioiil Thus it will be seen that the levers 11. and 12 cooperate with each other to control the operations of the vehicle, but

should their use beprevented it will beimpossible to start the vehicle.

The lever 11 is securedto a shaft '13 journaledin the frame 9, which shaft'is oper-, atively connected with the several mechanisms which are controlled bythe move nients of said hand lever. The lever or pedal 12 is secured or mounted uponia shaft 14 from which other, mechanisms .are controlled. vA casing 15 is secured to the body of the car, preferably beneath the platform or floor 10, and upon the side frame 9 in such a position that the pedal 12 will move parallel with said casing and in close proximity to the side 16 thereof,'see Fig. The hand lever 11 is adapted to operate through slots 17 and 18 in the bottom and 'coveifrespectively of the casing 15. l

The preferred method of accomplishing the desired result is to provide obstructions which may be locked within or outside of the paths ofthe operating levers l1 and 12, preferably when the hand lever 11 is moved to its extreme or rearvposition and the emer gency brake of the vehicle is applied. The obstruction for the operating lever 11 preferably consists of a bifurcated rocker member or latch 19 ,pivotally mounted upon a stud 20 upon the interior of the casing 15. The furcations 21 and 22 of the latch 19 when said latch is in its normal and closed position, extend transversely ofthe slots-17 and l8 upon opposite sides ofsaid operating erating lever which at this time-is at the rea r 15 guides 24 and 25 and a screw 26 extending lever, as shown in Fig. 2, this position indi-' cating the extreme-rear position of said opends of the slots 17 and 18.

A slide 23 is arranged to reciprocate within and longitudinally of the casing 1.5 in

through a slot 27 provided in said slide. 23. An actuator 28 is provided for said slide within. said casing and consists preferably of a-disk 29 having an axial extension or hub 30. -The hub 30 projects. outwardly from the casing and through an'opening 31 and lnto a tubular casing 32 which const1- tutes a journal or bearing for. said disk, said portion36 of the slide 23 when it 'is desired tubular casing projecting upwardly and through an opening 33 in the floor 10 of the car. a

The tubular casing 32 beneath the floor'10. The slide 23 and actuator 28 are operatively connected together by a link 35 pivotally' connected at its opposite ends to the members'23 and The end of the slide 23-is beveled at 36 to engage a corresponding beveled face 37 formed upon the latch 19;

The face 37 is engaged by the beveled to obstruct the movements of the hand lever 11 in the manner illustrated in Fig. 2, thus preventing the rocking of the latch 19 in the direction of the arrow at. A spring 38 is arranged in the slot'27yan'd is adapted 'toyieldingly retain said slide in contact with the'lat'ch 19.

I The inclination of the beveled face 37 is of such a degree ,thatfl-pressure applied against the furoation 22 of thelatch 19, by

means ofthe lever 11 in' attempting to 0perate: said lever, will notg bje 1, suflicient to cause the slide 22 to bewithdrawn or moved from beneath thelatch 19. These beveled faces however assist the spring 38in 'more readily positioning the obstruction or latch in its normal position. 1 i

A. spring 39 is arranged to engage the latch 19'adjacent the furcation 21 thereof and tends to rock said latch upon its piv ot 20in the direction of the-arrow a, or 1n opposition to the spring 38; When the slide,

23 is withdrawn and'the operating lever -11 is moved about its axis along the slot 17 the i 1 latch 19'willbe rocked upon its pivot 20 by the spring-39 until the furcation 22 has been withdrawn from "the path of the, lever 11.

" said lever.

- I is secured to the casing 15 preferably by screws 34 arranged The movement of said latch is limited'by the slide 23, which is permitted. to move toward the right, see Fig. 1, only until a shoulder 40 on said slide contacts with a bracket 41 which constitutes the guide 25. The rocking .movement of said latch-is not however sufh cient to withdraw the furcation 21 from across the slot 17, as will be seen'in Fig. 5,

thus said furcation will remain in the path.

protrude through an opening 45 in the wall 16 of said casing. .The protruding portion of said bolt rests immediately in advance of the lever.12 when said lever isin its rearmost position, as shown in Figs. 1 and 2, thus preventing the'forward movement of gages the inner face of the wall 16 and limits 2 :the distance to which said bolt'shall protrude from said casing:

A shoulder 46 on said-bolt en- The bolt 42 is slotted longitudinally at 47 tof-receive a stud 48. and a springf49, said spring engaging said stud'at one end of said slot for the purpose of retracting said bolt within said casing The actuator 28 is common tovthe slide 23 and the bolt 42 and is operatively connected with said bolt preferably by means of a pin 49 projecting upwardly therefrom and through a slot 50,

which slot is elongated to permitof-a slight 4 lost motion between said diskand said bolt and to-permit the spring 49 to yieldingly act upon-v the bolt 42 to retract the same.

The actuator 28' isprovided with a lock mechanism 51 preferably arranged in the upperend of the tubular casing 32 and preferably consists of a tumbler-casing 52 secured within the upper end of the tubular casing 32 by screws 53 extending into said tumbler casing from the interior of said tubular casing. A cylindrical plug 54 is ro-.

tatably arranged within the tumbler casing "52, said plug having an annular shoulder 55 at its upper end adapted to limit the longitudinal movement thereof, while a disk 56 isseouredto the inner end of said plug and prevents thewithdrawal of said plug from said casing.

The disk 56 is adapted to interlock with the upper and outer end of the axial extension 39 through the instrumentalities of a tongue 57 formed on said disk engaging a groove 58-arranged at the outer end of said extension, thus when saidextension is rotated said plug will necessarily be rotated also.

The plug-54 is provided with an irregular slot 59 extending longitudinally'thereof and adapted to receive a key 60, said key having an irregularly serrated edge 61 adapted to receive tumblers (52 which are arranged within said plug' 5% and of such lengths that when saidkey 60 is within its slot in said plug, said tumblerswill all aline with the face 68 of said plug. The tumbler casing 52 is also provided with two series of tumblers 64 and (35 arranged in holes which aline with the tumblers 62. Springs 66 yieldingly retain said tumblers 6st in contact with the tumbler 62 when said sets of tumblers are in alinement and the key in position within the slot, permitting said plug to be rotated.

The two series of tumblers 6% and 65 represent the two extreme positions occupied by V I the actuator 28, thus when said key is with-- drawn at either one of said positions. said actuator will be held or locked in that position. A handle 66jextends from the hub 30 outwardlythrough a slot 67 in the tubular casing 32 in a convenient positionjabove'the floor 10 for the operator of the vehicle to manipulate, whereby said actuator "may operate when unlocked from one position or the otheras desired.

In theiconstruction of the device, as hereinbefore described, the obstructions for the levers 11 and 12 are maintained in their locking positions through the instrumentalities of the tumblers in the series 64 and to re- A spring 70 is arranged within a slot 71 formed in said locking slide and engages a stud 72 also extending through said slot for the purpose of securmg and holding the slide (37 in its position in the groove 8 and at the same time serves as an abutment for the spring 70.

The slide 67 is operatively connected with the disk. 29 by means of 'apin 73 which extends through a segmental slot 7 1 formed in said disk and of such a length that it will permit the locking slide 67 to be yieldingly moved between the rear end 75 of said bolt and the rear wall 69 of the casing, when said bolt is protruding from the casing as in Fig. 2. \Vhen the disk 29 is first rotated to withdraw said bolt from said lever 12, the locking slide 67 will be directly in the path of said bolt and prevent the withdrawal of said bolt. The slot 50 is therefore provided in the disk 29 to permit a partial rotation of said disk before engaging the pin'49,

which movement is sufficient to permit said and conveniently operatedl disk to withdraw the locking slide 67. from behind said bolt, but immediately upon bea ing released by said locking slide 67 the spring within said bolt urges said bolt to its rearmost position. The actuator disk '29 also operates a switch mechanism 76 to close an electric circuit including a pair of terminals 77 and 78 inclosed within the casing 15. 7

The switch mechanism 76 preferably embodies in its construction a slide 79 arranged the casing 15 and insulated therefrom by insulating material 81.' A collar 82 is secured to the slide 79 and is engaged by a spring 83 which has an abutment against one of the guides 80. I The slide 79 is adapted to be moved against the'action of the spring 83, between a pair of contacts 84 secured to an abutment 85 which in turn is mounted within the casing and insulated therefrom by insulating material 86. The contacts 8 1 and the abutto rec'iprocatein guides 80 mounted within ment 85. constitute the terminal 78 andto said terminal is secured, by means of a screw 87, one of the electric wires-8 8 included in' the ignition circuit, or preferably the circuit including the-lamps of-said vehicle. The

through a pipe 91 which prevents said wirefrom being tampered. withL'lThe slide 79 is operated to connect said terminals by means of a lug 92 carried by the slide'23,

said lug being adapted to engage the end of said slide 79 when said slide 23 is being withdrawn to free the lever 11 and thus push said slide-between the contacts84.

A catch 93 is pivoted at 94 within the easing 15 and engages a tooth 95 on theslide .79'when said slide 79 is in contact with the contacts 84, thus maintaining the switch mechanism closed. and the terminals 77 and 78 connected. A spring 96 yieldingly .retains said catch in contact with the tooth 95. By means of the spring catch 93 the switch mechanism may'be maintained closed even though the'levers 11 and 12, are locked in their inoperative positions which permits the operator of the car to leave the lamps of the vehicle lighted when he so desires, provided they are electric lamps. This catch is however adapted to be manually operated so that said slide maybe released and the terminals disconnected.v For this purpose a push pin 97 isarranged to project from the casing 15v through a tube 98 and above the floor 10 of said car where it may be easily The lower end of the pin 97 is pivotally p 130 attached at 99 to the, catch 93 in such a mancatch 93 will be withdrawn from the tooth 95, permitting the springs 83 to return the slide 79 to its normal position, as illustrated in Figs. 2 andl.

As a safety device for preventing the abutments 19 and42 from being moved into their locking positions, when the clutch lever 11 is forward, the furcation 22 of the latch 19, which constitutes the Obstruction for said lever, is provided with an extension 22. This extension, when said latch is thrown out of the path of said lever, as in Fig. 5, lies along and substantially parallel with the side of the slot 17 and overlaps the lever 11,-when in its forward position, thus absolutely preventing the rocking of said latch into its obstructing position until said operating lever 1-1 has. been returned to its nor- 'mal. position between the furcations 21 and 22 of said latch.

The general operation of the device hereinbefore specifically described is as follows: Assuming that the vehicle ire-inoperative and the operating levers v11 and 12 are in the positions indicated in Fig. 2, the'operator places the key 60 in' 'the slot59 to unlock the plug 54. He then-grasps thehandle 66 and moves the same from the full line position in Fig. 7 to the dotted line position therein, setting into motion the disk 29. The first part of the movement of said disk 29 causes the pin 73 to engage the right-hand end of the slot 7 4i and thereby withdraws the looking slide 67 from the end of the bolt 42, which bolt at this time is permitted to remain stationary by reason of the slot 50.

As thelocking slide 67 clears said bolt 42 the spring 49 withdraws said bolt from the path of the lever 12,-permittingsaid lever to be operatedwhen desired. Simultaneously with the movement of the slide 67 the slide 23 through the link 35 is withdrawn from the latch 19 and the spring 39 rocks said latch upon its. pivot 20 into the position illustrated in Fig. 5, leaving the lever 11 free to be operated when'desired. The move -ment-of said slide 23 also'causes the lug 92 toengage the switch slide 79 to move said slide toward the right Fig. 2' into contact witht'he contacts 84, thereby connecting the electric circuit terminals 77 and 78. vehicle is now in a condition to be started andoperated. After the vehicle has been stopped and the levers l1 and 12 returned to their normal positions and-it is desired to 'tion Fig. 7 which causesthe bolt 42 to be operated to protrude from the casing in the path of the lever 12 and the slide 23 to engage the latch 19 and rock the same from the positi'on'illustrated in Fig. 5 to that illuswe claim and left closed in order that the lamps of the vehicle may. remain lighted. lit this is not desired the operator depresses the push pin. 97 .'to release the slide 79 permitting spring 83 to return said slide to its inoperative normal position, thus disconnecting the terminals 77 and 78. The key 60. is then withdrawn from the slot 59 leaving the vehicle safely and securely locked.
